The 1.5-mile parade will travel south on 7th to Chouteau, east on Chouteau to Broadway, south on Broadway to 7th Street and then south on 7th Street, eventually ending at Sidney.

Everyone attending the event must be at least 21 years old to consume alcohol. Officials say undercover officer and city agents will be looking out for underage drinkers and those caught using a fake ID could be arrested.

Checkpoints will be along the perimeter of the neighborhood to prevent anyone attending the Mardi Gras festivities from bringing in coolers, backpacks, cans or bottles into the festival area.

Anyone caught urinating in public will also be subject to arrest. Officials hope the portable toilets scattered throughout the area will prevent that from happening.

Officials say all vehicles parked along the route will be towed. Vehicles will also not be allowed inside the Soulard Red Zone, which is defined by the following areas: Marion on the north, Broadway on the east, I-55 on the west and Shenandoah from Broadway to 11th and Ann from 11th to I-55 on the south.

Anyone with a permit will be allowed to park in the Yellow Zone, however. That zone is marked by the following streets: Ann from I-55 to 11th and Shendandoah from 11th to Broadway on the north, 7th on the east, Lynch on the south and I-55 on the west.

These streets will be completely or partially closed on Saturday: Clark from 8th to Broadway and 6th from Gratiot, as well as the entire Red Zone as mentioned above.
